离子交换

When deacidification with resins,the flow rate is an important effect factor. The slower the flow rate, the higher the volume of kiwi wine obtained, three weakly basic anion exchange resins, for the absorption order of the main organic acid of kiwi wine , citric acid is first, malic acid is the second, the last one is quinic acid.
